Pianist Dale Tsang will perform Judith Shatin's Scirocco twice under the auspices of Ensemble 4 These Times (E4TT), first on Feb. 22 at 7:30 pm at the Berkeley Piano Club in Berkley, CA, and then on March 2 at 4:00 p.m. at the SF Music Center. Named for the hot wind that sweeps up from the Sahara to the Mediterranean, it is a short whirl of a piece that is newly published by ACA.
